Definitions

  • the invention relates to supports with inflatable pockets for seats of motor vehicles, covered with padding and which are connected to an adjustment system.
  • the utility model DE-GmS 76 17 960 discloses a back support consisting of pneumatic chambers in the form of sleeves made of an elastic material. Pumps each fitted with an exhaust valve allow the internal pressure to be adjusted individually and the back support to be adapted to the needs of the seat user.
  • Publication FR-A-2 265 347 describes a seat carrying lateral supports formed by ball pockets stretched respectively over the seat frame by means of a strap passing through the eyelets placed around the periphery of the pocket.
  • the set of pockets communicates by pipes so as to facilitate the establishment of a relative vacuum and to obtain cohesion of the balls necessary for the production of a sufficiently rigid support molding the seat user.
  • the publication FR-A-2 276 798 describes a device for mechanical adjustment of the lateral supports of a seat back.
  • the known devices do not allow the production of seats in which the inflatable pneumatic chambers, because of their elasticity and their hardness, are located in the vicinity of the trim and the load surface of the seat.
  • the invention proposes a solution to the aforementioned problem and has for its object a seat whose pneumatic lateral supports can be adjusted manually or automatically from an independent pressure source.
  • the invention therefore relates more particularly to an inflatable bag support resting on a suspension element and connected to a filling device.
  • the pocket is placed between two flaps, one of which is fixed to the suspension element and the other of which is mounted in mobility relative to the first flap under the effect of the inflation or deflation pressure. out of the pocket.
  • the support thus produced can easily receive a cushion provided with an external coating of appearance and greatly improves the comfort and the maintenance of the seat user.
  • FIG. 1 schematically represents a seat frame carrying two lateral support supports applied to a seat cushion.
  • Figure 2 shows an inflatable pocket held between its two flaps.
  • Figure 3 is a sectional view of the flap mounting system on the seat with section of the pocket and flaps along line 3-3 of Figure 2.
  • the frame 1 of the seat supports a hanging frame 2 with load springs 3.
  • the front transverse side of the frame 2 is suspended on the frame 1 using coil springs 4.
  • the lateral sides of the frame 2 respectively carry two sets of two flaps 5, 6 joined to each other by means of a plastic hinge 7.
  • the flap 5 is fixed to the frame 2 in connection with a load spring 3 arranged longitudinally along the lateral sides of the frame 2 so that the opening of the flaps 5, 6 is oriented towards the lateral side of the seat.
  • the shutter 6 is covered by the padding lining 8 supplemented by a covering fabric 9 stretched between the opposite elements of the frame 1.
  • an inflatable bag 10 supplied by an air pressure source 11 capable of being vented by means of a valve 12.
  • the pocket 10 carries at its periphery eyelets 13 for fixing by means of clips 14 to the flap 5.
  • the shutter 6 is thus made movable relative to the shutter 5 under the effect of the inflation or deflation pressure.
  • the latter In order to prevent the pocket 10 from sliding out of the flaps 5, 6, the latter carries positioning pins 15 engaged in the housings 16 carried by the flap 6.
  • the flap 6 could be fixed on a load spring of the file while the flap 5 will rest on a suspension ply and on a frame element of the file.
